"Since necessity plays a central role in the generation and regulation of this kind of architecture, I associate it with natural forms known as stalactites and stalagmites, where the shape is the result of a fluid movement of materials attracted by gravitational force. In this popular architecture, the irrepressible movement of materials also produces a grid of lines and holes, a superimposition of layers and structures that, just as in the natural process of sedimentation, are supported one over the other. This fluid movement responds to a strength as powerful and unavoidable as gravity, the force of necessity.”
Ernesto Oroza from For an Architecture of Necessity and Disobedience, 2006.
